Each group came up with a different solution. Our solution was to move the pillars from one side 11 cm closer to the other side. Another group added 5 cm of metal on one side and 6 cm on the other side. One group decided the pedestrian bridge was too expensive and made improvements to the existing crosswalk instead.
After we made our blueprints and picked out our materials, our group built the ramps. Then, guess who came into our classroom? Someone from CBC radio and TV came to interview us when we were constructing our bridges.
I learned that building a bridge takes longer and is more complicated than I thought. Sometimes keeping our group on task and working together was tricky. But I really liked constructing the bridge and seeing our class on CBC. And I'm excited to walk over the bridge when it's ready for pedestrians like me!
